How much fat is okay?

by Dr Wynnie Chan

question
What is the difference between a diet with 2,000 calories and 65 grams of fat and a diet with 2,000 calories and 30 grams fat? Would eating less fat mean you gain less weight or lose more weight?

answer
The recommended healthy amount of fat in your diet involves an eating plan that gets no more than 35 per cent of its energy from fat. A diet containing 65g of fat will provide 30 per cent of its food energy from fat, whereas a diet containing 30g of fat will provide only 14 per cent of its food energy from fat.

One gram of fat contains nine calories, compared to one gram of carbohydrates, which contains only 3.75 calories. This makes fat a much richer energy source.

Weight loss or gain all comes down to the number of calories you eat versus the number of calories you burn off. To lose weight, you need to shift this balance so you burn more calories than you eat. Generally most people can lose weight by reducing their calorie intake by around 15 per cent. The best way to do this is by following a low fat/high carbohydrate, low calorie diet, which will fill you up without loading on the calories. Combined with a regular exercise regime, this should help you achieve a sensible weight loss of one-two pounds per week.

So the simple answer to your question is, the percentage of calories coming from fat is greater in a diet containing 65g of fat, compared to a diet containing 30g of fat, and is therefore more likely to impede weight loss.
